WINDOW-CONTROL IVIECI-IANISVI.

Application led January 7,

The invention relates to a lwindow control .so arranged that the force applied therethrough for raising or lowering a window is applied longitudinally of 'the window and substantially in the longitudinal median line of the same. Another object is the provision of a mechanism which is compactly arranged and which provides a leverage which is greater than that secured by a lever of the same length as the mechanism. Further objects of the invention reside inthe novel :teatures of construction and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawing: Figure l is an inside elevation of a vehicle door with the lining removed and showing a window control mechanism embodying my invention;

Figure 2 is a cross section on the line 2-2 of Figure l.

1 is the door of a motor vehicle having in its upper portion the opening 2 and in its lower portion the pocket 3. 4 is the window or closure vertically slidable in guideways in the hinge and lock pillars of the door frame, and 5 is the lockboard extending between these pillars.

Y To raise and lower the window 4, I have provided mechanism in the pocket Slot the, door and operatively connected to the window 4 at the middle of the channel 6 einbracving its lower edge. This mechanism is so arranged that the force applied therethrough is substantially in a vertical plane. In detail, 7 and 8 are like levers which are pivotally mounted at their inner ends upon the hinge pillar oi the door trame. These levers converge toward each other from their pivotal mountings and their outer ends are pivotally connected to the arm 9, which latter extends from the outer ends of the levers towards their inner ends and isk pivotally connected at 10 to the middle of the channel 6 embracing the `lower edge of the window. lVith this arrangement the pivot l0 remains at all times in substantially the vertical plane passing through the longitudinal center of the window owing to the fact that the swinging movement of one lever will compensate for the swinging movement of the other le- 1924. semi No. 684.869.

ver. IIowever,V to allow afslightvariation from the verticalr plane through `the center of the window sufficient play is allowed for the pivot.

lhe mechanism raisedand lowered byl suitable ineans,-which in the present instance comprises 'thescrew'll engaging tl'ieniit 12 y swivelled upon the loweil arm and driven from suitable gearing in the gear vcasali-3,

which latter is mounted upon the loclboardV 5. lll is a coil spring for.counterbalancing the window and also the l-evers and arm of the window cont-rol mechanism.

lTo provide a unit mounting `for the levers.

and the coiiiiterbalancing spring oi" the window control mechanism, I have provided the support l5 which is secured to the hinge pillar of the door frame by suitable mechanism such as the screws 16. The upper and lower ends of this support have cars 17 and 18 through which extend the pivots toi' connecting the inner ends of the upper and lower the window owing to the fact that the point" or pivotal connection between the pair of levers and the arm travel through arcs which p coinpensatevtor each other. It will also be secu that the leverage secured with my construction is decidedly 'greater than that secured by a lever ol' tliesame length as my mechanism.' Furthermore, "that I have provided a unit mounting for the leversv and counterbalancing spring of the mechanism.

What I claim as my invention is: l. The combination with a frame and a closure slidable in said frame, of a pair of similar levers extending transversely of the path oi travel oi'i said closure and pivotally ally connected to said levers and operatively connected to said closure, said arm extending s from its point olf pivotal connection with said levers toward the point of pivotal mounting of said vlevers and being Vperatively connected to saidclosure. n f f lmounted upon said iframe, and an arm pivot- 2. The combination with a frame and a closure slidable in said frame, of a support uponv said frame, a pair of levers pivotally mounted upon said support, an arm pivotally connected to the free ends of said levers and operatively connected to said window, and

- a counterbalancing spring connected to said support and one of said levers.

3. The combination with a frame and a closure slidable in said frame, of apair o1 levers extending transversely of the path of travel oi said closure and pivotally mounted upon said iframe7 a device operatively connectedat spaced pointsA to said levers and also operatively connected to said closure, said device being angularly movable upon movement of lsaid levers whereby the point of connectionibetween said device and closure moves in a substantially straight line, and

means for actuating one of said levers and thereby actuating said device and closure.

4. The combination witha frame and a closure slidable in said frame, of a pair of levers extending` transversely of the path ot' travel of said closure and pivotally mounted upon said frame, a triangularly-shaped de vice having its base portion operatively connected at spaced points to said levers and being pivotally connected to said closure at its apex, said device being angularly movable upon movement `of* said levers whereby the' point of connection between said device and closure moves in a substanti ally straight line, and means for actuating one of said levers and thereby actuating said device and closure.`

In testimony whereof I affix my signature.
